Detailed Description

Standard Ignition TX199 is an engine coolant temperature sensor for select Volvo XC90 and Volvo S80 models. It is used to report coolant temperature to the vehicle’s engine management system, helping the ECU monitor operating conditions and respond to temperature changes. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. If you are replacing a Volvo XC90 coolant temperature sensor or a Volvo S80 engine coolant temperature sensor, TX199 provides the specified connector style, terminal layout, and mounting method for the listed applications.

Vehicle Fitment

• Fits 2005-2011 Volvo XC90, N/A
• Fits 2007-2009 Volvo S80, N/A

What It Helps Solve

• Incorrect coolant temperature readings
• Hard starting related to temperature signal errors
• Engine warning lights tied to coolant sensor faults
• Rough idle or drivability issues from inaccurate temperature input
• Cooling system control problems caused by a failed sensor

Installation Notes and Tips

Confirm the connector shape, terminal count, and bolt-on mounting style before installation.
